StandardDetails

This specification establishes the physical requirements, sampling, testing, and visual inspection of architectural cast stone that may be made from facing and backup mixtures or from a homogeneous mixture, produced either by wet or dry casting. Conformances for raw materials, Portland cement, aggregates, coloring pigment, reinforcement, chemical admixtures, air entraining admixtures, water reducing and accelerating admixtures, ground slag, fly ash or natural pozzolan, and other consituents shall be precisely observed. Products shall also conform to specified physical and performance requirements such as compressive strength, cold water absorption, boiling water absorption, air content, field testing, resistance to freezing and thawing, and linear drying shrinkage.
